Recommendation: Plan a near-term fix — a public PoC already exists.
R 3.4.4 contains a local buffer overflow vulnerability that allows attackers to execute arbitrary code by injecting malicious input into the GUI Preferences language field. Attackers can craft a payload with a 292-byte offset and JMP ESP instruction to execute commands like calc.exe when the payload is pasted into the Language for menus and messages field.
